Hacked together IDEX with 5 controller boards.
I hacked together a cartesian IDEX 3D Printer of parts I had laying around. The goal was to make a test platform for the tiny 3D printer controller boards I am working on, github.com/bondus/KlipperToolboard.
Both heads and X axis (two of them) are using the toolhead board, communicating to the Raspberry Pi over CAN bus. Y and Z and the hotbed are run by an SKR Mini board.

Five bar scara agility and speed
Просмотров 4,4 тыс.4 года назад
Showing off some moves of the machine. Acceleration is set to 6000mm/s^2 and speed to 1500mm/s (not sure it reaches that). I should make the "forearms" longer to get better reach on the sides and back.
Five Bar Parallel Scara, v2

Second version of my design of a Five Bar Parallel Scara 3D printer. This one is far better than to old one and produces pretty good looking prints.

Using foot force sensor and a 6-axis MPU the robot does it best to always keep at least 3 feet on the ground and maintain static balance.

Finally got the battery electronics working and the wireless communication and the kinematics calculations and some very basic gait logic. Everything is still on open loop. It is controlled using a game controller. Mainboard is now a Teensy 4.0, a very nice little board.

First steps of a little quadruped robot. It seems work fine mechanically. Hopefully it will be a platform for some machine learning
Five bar robot leg

The good old five bar kinematics (with an extended arm) seems to be well suited for a leg of a quad walker robot. It naturally creates a good step with very simple controls.

are blueprints available anywere? I like vvery much this printer, I'd like to make one
What firmware do you run for this? And what kinenatic? Im very interested. I would like to talk to you in private if you want :)
i wonder if it wold work well as a 3d printer
it would be hard to stop sag
It has twice as many arms compared to a regular scara 3d printers so I'm guessing sag won't be a problem with this one.
Awesome 👍
parallel Scara better than delta and polar 3d printer
hello i just want to start a project to relax after work is there any chance that you shared the files some ware as i was looking for something like this for quite some time
Beautiful! good work :D
Hello I just thought about building the same thing , do you think that you can share the files for it as I will like to make my own version but I do not have a lot of knowledge in code writing
Hanzhen harmonic drive gear , over 30 years experience , strain wave reducer , robot joint

do you have tutorial how to make it?
So just curious what is the advantage to this over a more traditional printer?
More headaches... if that's your thing...
Hello. I love this, it's amazing! Where I can get firmware?
I would love to build something like this...where should i start?
gorgeous machine!
I feel like pretty much all of that could be 3D printed
How does the gcode work?? I feel like no slicer program would work with this because the axis' are very abnormal in that there is really no X or Y.
The gcode work in normal XYZ directions. The firmware in the control boards does the translation to arm positions.
very very successful
Great. Thanks again.
But why...?
What are the advantages with respect to a cartesian 3D printer?
Parallel robots are capable of high speed/high presition movements.
It's a really cool robot, but I can't help but notice that it seems to be walking over a pile of its own body parts, which is a little disturbing
If you built it upside down with the stepper motors above the centre of the build plate, couldn't you have a way bigger build area?
Amazing work!
it's amazing!, I hope you can share your work, if it is already open source it would be spectacular, I would love to do a job like yours, I really liked it a lot, congratulations and thank you for sharing the video
The software to run it was made a part of RepRap firmware, Five Bar Scara.
@@boxsterpontus Thaks, i will look taht
Hello, would you share the firmware? my email is ekranoplan zapatero@gmail.com
so silent!
A little late to the party, but would this benefit from counterweights? It would increase the cost (Many more joints) and the moving mass, but it should remove a lot of the torsion from the main bearings.

Cool design and I am sure you have fun with it, but it isn't very practical as it takes so much more space than traditional 3D printers.
It's a proof of concept, a prototype machine to test if the idea is any good. It is a good idea. Check out www.kickstarter.com/projects/plybot/plybot
@@boxsterpontus Yes, that's what I am saying. I am sure it's fun to build and to watch it, but I see no practical use for it, other than fun, since the accuracy and the speed must be much worse than traditional design. Also not very practical considering the needed space, since it needs more space for the same print area. Never the less, I like the idea, but in my opinion, it is not suitable as a 3D printer, even if "it works". But we have different goals, YMMV.
Why do you think this takes more space.. bedslingers or any other design all have wasted space.. And if you'd wanted an idex printer you could just make another bot, keep it beside this one and boom. Truly scalable idex capability.
@@padmanabhaprasannasimha5385 If you can't figure it out then just have a look at the arms left and right movement. That is about three times (in fact more than that) as much to the actual work area. The forward and reverse movement waste is about 50% of the work area. A traditional 3D printer waste area is considerably less than that, in fact it is only about twice the work area in one direction and about 50% in the other. Never the less, this one would impress on your friends much more than a traditional 3D printer.
Wonderful. Do you publish the firmware? Can it be customized in GRBL?
That was mental, can extruder actually keep up with that speed?
That looks like the Tesla snake changer prototype
James Bruton would like to know your location
How it wraps around itself would be so amazing for many small parts on a U shaped buildplate
Amazing work, is it an open source?
This is so damn cool! Nice work! Been tempted to try this kinda kinematics
are there any pressure sensors in the feet? Great job!
Yes, there are some force resistors under the pads on the feets. It made a massive difference for its capabilities to walk good on uneven terrain. Balance and algorithms are still pretty simple.
@@boxsterpontus Wow! having such small force resistors in those tiny feet must be seen as an accomplishment! Great job!
WHOA! thats crazy!
Do you happen to still have the stls?
I am very much interested in building my own for personal use and a fun learning experience. Where can I find the software or guides on building one of these?
klipper
Also do you have an update on the code? I am looking to build a scara robot 3d printer such as one here.
Wouldnt you benefit if the z axis only moved the plate and not the entire assembly?
Fantastic project! Any plans to share code and hardware design? Looking to get into my first robotics project, but lack the skills to start from scratch.
this is dope, i run a facebook 3d printing group facebook.com/groups/iloveto3dprint - you should join
Nice work ! I'm wondering why you removed the redondant bar from shoulder to elbow like we can see on V1. Wasn't improving the stiffness of the arm ?
Nice, but the scara is dead?
You spotted the scara back there! It's certainly not dead, it's just lending it's z-axis and bed for this horribly wobbly IDEX.
This is very neat!
one of the most creative printer design i have ever seen
Well done! I laughed out loud when it went off the print bed! Amazing work. This is definitely the future of 3d printing
Is your logo the workspace of this type of robot? :)
It sure is. The face popped up when I was playing around with different arm lengths. I call him Scaraman
@@boxsterpontus I've done hundreds of workspace analysis of the robot and never saw a face until now. Love the Scaraman haha!
